arXiv:2605.26678v1 Announce Type: new Abstract: Long-context language models are limited by the memory footprint of the key-value (KV) cache. Existing training-free KV compression methods usually rank tokens by one importance signal -- attention, recency, layer-wise allocation, or key distinctiveness -- which becomes brittle when useful context is globally distinctive, locally episodic, or immediately relevant. We introduce NestedKV, a key-only KV cache compression method inspired by the Continuum Memory System in Nested Learning. NestedKV maintains global, block-level, and sliding-window key
The development of long-context large language models is currently limited by KV cache memory, driving research into innovative compression techniques like NestedKV.
Efficient KV cache compression directly impacts the scalability and cost-efficiency of long-context AI models, enabling more complex and capable applications.
This advancement could significantly reduce the memory footprint for long-context language models, making them more practical for deployment and further development.
